Problem With US "Energy Independence" - Reserve + "New" Tech Not Same As Sustainable Flow Rates

EDIT

The relationship between energy and the economy is the most important thing that anyone can, and should, work to understand. In the past, we've always had whatever amounts of oil we wanted to support the sort of economy we operate, and that happens to be an economy that grows exponentially. The rate of growth that seems to work best at about 3% real and 6% nominal growth.

Now, between the 1960s and the 1980s, the world saw roughly a 6% per year growth in oil output. From 1980 to 2000, roughly 1.5%. And since then, almost flat, maybe a .1% growth in oil output. So shale oil discoveries may be massive in terms of the total number of barrels of oil--but what they lack are high and sustained flow rates. And there's a lot of confusion out there in the press right now, with several analysts that should know better, waving their hands at increasing reserves and then making the utterly wrong conclusion that peak oil is a defunct theory.

Now, to illustrate this, imagine we just found a trillion barrels 40,000 feet down. Yeah, that would awesome, right? No more peak oil, at least for a long time, right? Well, what if due to technological considerations, we could only get a few wells installed, and the max flow rate we could get from that reservoir was 100,000 barrels per day. Oh, that's it? Well, that's nice, but it doesn't really help the overall situation, where we're experiencing roughly 4,000,000 barrels per day,per year declines in existing conventional crude oil fields. That is, reservoir size and flow rates were well-correlated several decades ago, because the stuff just flowed out of the ground so easily, but now that we have to drill tens of thousands of feet to achieve a single well flow rate on the order of 100 barrels per day/per well in the shale plays, or we even have to scoop up tarry sand in giant machines and then power wash the bitumen off of it, oil just don't quite flow quite like it used to.

There's a new relationship between reserves and flow rates, and it's a fraction of the old rate. And it's an entirely new world, and this has been missed by the less insightful analysts and commentators out there. I am optimistic about the new reserves and flows but not because I happen to think they allow us to forget about the challenges and snap back to 'how things used to be.' We're in a new regime of higher oil prices and that alone sets today well apart from the past.
